Abstract

We provide a direct comparison of the distribution and abundance of mycosporine-like amino acids (MAAs) in a diverse range of microalgal cultures (33 species across 13 classes) grown without supplementary ultraviolet radiation (UV). We compare the MAAs in cultures with those present in characterised natural phytoplankton populations from the English Channel. We detected 25 UV absorbing compounds including at least two with multiple absorption maxima. We used LC-MS to provide chemical characterisation of the six most commonly occurring MAAs, namely, palythene, palythine, mycosporine-glycine, palythenic acid, porphyra-334 and shinorine. MAAs were abundant (up to 7 pg MAA cell−1)in 10 species, with more minor and often unknown MAAs in a further 11 cultures. Shinorine was the most frequently occurring and abundant MAA (up to 6.5 pg cell−1) and was present in all but two of the MAA-containing species. The study provides further insight into the diversity and abundance of MAAs important from an ecological perspective and as potential source of natural alternatives to synthetic sunscreens.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • More than 30 MAAs are produced by algae and cyanobacteria.

    “There are more than 30 MAAs produced by algae [117] and cyanobacteria [118]”

    From UV Filters: Challenges and Prospects (2022) · cites this paper as [117]

    The Introduction says MAAs occur in algae, but it does not establish that algae produce more than 30 distinct MAAs: it describes a group of over 20 compounds and says at least 19 structurally distinct MAAs had been recognized. Results and Discussion §2.1 reports 25 MAA or MAA-like compounds across 33 algal species; the 33 counts species, not compounds. The separate citation for cyanobacteria is not judged here.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
